i went to do some research about white hair. they say that only severe stress would cause hair to turn grey. i don't think i am under severe stress. so maybe its the genes. but my mother only started to have white hair at 30+. could it be the they difference in the childhood? The report also said that under severe stress a person would look alot older then his/her age... and i have been mistaken for being older before. So tell me do i look older then 15???
